The former Everton and Tottenham midfielder has been a free agent since being released from his contract at Como before the start of the season.
Alli still had a year to run on his Serie A deal, but it was mutually agreed to end the arrangement.
The former England international has remained without a club since then, though has been undergoing personal training.
And this week, Alli took to social media and posted an image of himself kitted out and with a football at his feet, along with three hearts.
Alli has been linked with Birmingham City and Wrexham in recent months.
